ABSTRACT

Introduction: The craniopharyngioma is a histologically benign neoplasia that may have a component cystic (rich in cholesterol), solid or complex; knowing the characteristics of the Magnetic Resonance Imaging (MR) allows determining with precision the extension in the central nervous system of said pathology, establishing the surgical adequate planning, besides the imaging characteristics may suggest the histological lineage. The craniopharyngioma represents the 3-4% of all the intracranial neoplasias, 15% of suprasellar tumors, 50% of sellar tumors in pediatrics, the third most common non glial intracranial tumor and the more frequent that affects the hypothalamushypophyseal region; seven of every 10 craniopharyngiomas are suprasellar. During childhood, it shows a bi-modal age distribution, peak of first age and second decade.
Material and methods: From the Magnetic Resonance studies accomplished at the Hospital General of the CMN “La Raza”, from January 1st, 2006 to January 1^st, 2008. The CMN accomplished a revision in retrospective in eight cases of craniopharyngioma registered in the Neurosurgery Pediatric Service of the Hospital General “La Raza”; we checked the characteristics through MR taken in the imaging revision through the radiological digital file.
Results: The age distribution predominated between the 10 and 11 years old, the location was suprasellar in five cases; the size of the injuries ranged from 2 to 9 cm; cystic injuries in four patients were observed (50%), mixed, this is both, cystic as solid in four patients (50%). The morphology that predominated was multi-lobar in six patients (75%).
Discussion and conclusions: The most frequent location was suprasellar that coincides with what reported in literature; no series exists that quantifies the extension of the injuries by cm. In our work, it ranged from 2 to 9 cm with a 5.6 cm median, this related to the presentation of the clinical data more than to the biological activity of the injury. The most frequent complication is chyasmatic compression, as well as the compression to adjacent structures, depending of the size of the tumor, the hydrocephalus showed up even in 75% of all the patients and it was secondary to the size of the injury. Our findings are congruent in general terms with what’s described by other authors.
